SOLDERING-IRON.

PBCIPICATIN forming part of Letters Patent No. 381.533, dated April 24,1888.

Application filed January 21, 1885. Serial No. 261,521. (No model.)

To @ZZ whom it may concern: l

Be it known that I, CARL R. DaNInLsoN, a subject ofthe King of Sweden,and residing at Rockford, in the county of Vinnebago and State ofIllinois, have invented certain new and useful Improvements inSoldering-Irons, of which the following is a specification.

This invention relates to a class of soldering irons known as theselfheating solderingiron.

Its object is to improve this class of soldering-irons to render themmore efficient.

To this end I have designed and constructed the apparatus represented inthe accompanying drawings, in which- Figure l is a plan View of anapparatus embodying my invention. Fig. 2 is a side elevation. Fig. 3 isa vertical lengthwise central section. Fig. 4 is a section of the valveFig. 5 is a side elevation in which the solderingviron is removed andthe holder fitted with a nozzle to adapt it for certain uses.

In my improved self-heating soldering-iron a reservoir, I, to containthe liquid fuel is preferably of cylindrical tubular form, with open endfitted with a removable cap, 2, through which the fuel is admitted tothe reservoir. The end portion, 3, of the reservoir is of reduceddimensions to receive a packing, 4, which serves to regulate, in amanner, the ow ofthe liquid fuel to the burner. The reduced end portionof the fuclreservoir isprovided with a radial opening, 5, whichcommunicates with a reduced opening, 6, the open end of which forms thevalve-seat, preferably of conic form. A valve, 7, fitted with conic endto engage the valveseat, is provided with a screw-thread connection withits support 9. The support 9 ofthe valve 7 is provided with astuffing-box, 10, of the usual construction.

A chamber, 1I, is formed in the end ofthe fuel -reservoir, and anoblique opening, I2, connects this chamber with the fuel reservoir bymeans of a horizontal opening, I3, which connects the oblique opening I2with the opening in which the valve-stem is supported, between thescrew-threaded portion of the valvestem and the valve-seat, in such amanner that when the valve is removed from its seat the liquid from thereceptacle will rise through the radial opening 5, pass through thereduced opening 6,throughthe valveseat, and thence through thehorizontal opening 13 and oblique opening l2 into the chamber 11.

A combustionchamber, 14, preferably of tubular form, has ascrew-threaded connection with the reduced end portion of thefuel-reservoir,and this chamber is provided with a transversepartition-wall, l5,which,when the combustion-chaniber is screwed intopositiomwill engage the end of the fuel-receptacle, forming an outer endwall to the chamber l1. The transverse portion l5 is centrally providedwith a pin-opening, 16, through which the fuel is admitted to thecombustion-chamber.

The combustion-chamber 14 is provided with a series of lengthwiseopenings, 17, to admit air to support combustion, near the end at whichthe fuel is admitted.

A thimble-form damper, 18, is fitted to slide lengthwise on thecombustion chamber to open and close the openings 17 to admit more orless air to the chamber.

A soldering-iron, 19, is employed, having its free end 20 shaped iu theusual form. The soldering-iron is centrally bored at its upper end abouthalf-way of its length, and on one side toward its upper end is providedwith an opening, 2l, to admit the dame from the combustion of the fuel.It is also provided with transverse openings 22, to permit the escape ofthe products of combustion. This soldering-iron is provided withyoke-hars 23, fixed to its upper end portion, from which they project atabout right angles to the solderingiron on the side thereof in which theopening 21 is formed. The bars 23 may be bolted or screwed to thesolderingiron, or they may be formed integral therewith, as may be founddesirable. This soldering-iron, by means of its yolrearms, is removablyconnected to the end portion of the fuel-reservoir by means ofbolts 24,passed through the parts which hold it in connection with thefuel-reservoir in such relative position therewith that the products ofcombustion will be driven into the central opening through the opening2l, to escape through the lateral opening 22 and through the upper endof the central opening. A damper, 25, is pivotally connected between theyoke-arms to swing into position to close the upper end of the centralopening of the soldering-iron, or to swing upward therefrom to permitthe es- IOO cape of the products of combustion upward through thecentral opening of the solderingiron.

A metallic jacket, 2G, incloses'the main portion of the soldering-iron,and an asbestus packing, 27, is placed between thejacket and thesoldering-iron to retain the heat produced by the combustion of thefuel.

.The fuel-reservoir l is jacketed by an asbestns coating, 28, fixed inplace by a cord, 29, Wound thereon, or other suitable outer coating,which forms the handle portion of the apparatus.

A nozzle, 30, is fitted to the outer end of the combustionchamber, to beemployed when the soldering-iron is removed from its connection with thefuel-reservoir, and is intended to be employed in soldering verticalseams or in other situations in which it may be found inconvenient touse the soldering-iron.

In the use of my improved soldering-iron the screw-cap 2 is firstremoved, the Wick et inserted into the reservoir, the reservoir thenfilled with the liquid fuel of any suitable variety-sueh as gasoline orother like fluidsand the cap replaced,which fits the apparatus for use.

To use the apparatus, withdraw the valve sufficient to admit a flow ofthe fuel to the chamber ll to generate a gas, which is forced 3o throughthe pin-opening 16 into the combustion-chamber, where it is ignited andforced into the soldering-iron to produce the heat required, Which maybe regulated by means of the valve and dampers heretofore described.

I claim as my invention-- l. rlhe combination, With the fuel-reservoir,the soldering-iron, and the burner, the fuelreservoir being providedwith laterally-extending lugs, of yoke-arms fixed to the soldering-ironat one end, said arms being removably secured to the saidlaterally-extending lugs on the fuel-reservoir, substantiall y as setforth.

2. The combination, with a hollow soldering-iron, of a damper to controlthe escape of the products of combustion, substantially as set forth.

3. The combination, with the soldering-iron, of a metallic jacketembracing the solderingiron, and an asbestus packing between thesoldering-iron and the metallic jacket, substantially as set forth.
